MPI_Open_port - Establish a server port for client MPI
connections
SYNOPSIS
#include <mpi.h>
int
MPI_Open_port(MPI_Info info, char* port_name)
INPUT PARAMETERS
info - extra information handle
port_name
- newly established port
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and
MPI_WTICK ) have an additional argument ierr at the end of
the argument list. ierr is an integer and has the same
meaning as the return value of the routine in C. In For
tran, MPI routines are subroutines, and are invoked with
the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of
type INTEGER in Fortran.
USAGE WITH IMPI EXTENSIONS
The IMPI standard only supports MPI-1 functions. Hence,
this function is currently not designed to operate within
an IMPI job.
ERRORS
If an error occurs in an MPI function, the current MPI
error handler is called to handle it. By default, this
error handler aborts the MPI job. The error handler may
be changed with MPI_Errhandler_set ; the predefined error
handler MPI_ERRORS_RETURN may be used to cause error val
ues to be returned (in C and Fortran; this error handler
is less useful in with the C++ MPI bindings. The prede
fined error handler MPI::ERRORS_THROW_EXCEPTIONS should be
used in C++ if the error value needs to be recovered).
Note that MPI does not guarantee that an MPI program can
continue past an error.
All MPI routines (except MPI_Wtime and MPI_Wtick ) return
an error value; C routines as the value of the function
and Fortran routines in the last argument. The C++ bind
ings for MPI do not return error values; instead, error
values are communicated by throwing exceptions of type
MPI::Exception (but not by default). Exceptions are only
thrown if the error value is not MPI::SUCCESS .
while MPI functions will return upon an error, there will
be no way to recover what the actual error value was.
MPI_ERR_OTHER
- Other error; use MPI_Error_string to get more
information about this error code.
MPI_ERR_INTERN
- An internal error has been detected. This is
fatal. Please send a bug report to the LAM mailing
list (see http://www.lam-mpi.org/contact.php ).

MORE INFORMATION
For more information, please see the official MPI Forum
web site, which contains the text of both the MPI-1 and
MPI-2 standards. These documents contain detailed infor
mation about each MPI function (most of which is not
duplicated in these man pages).
